Overview
To diagnose dengue fever early and accurately the Dengue Rapid Test Antigen (NS-1) and Dengue Antibody (IgM IgG) Test are necessary. Early detection usually within 1–7 days of symptom onset is critical because the NS1 Antigen test finds the dengue virus in the bloodstream during the first few days of infection. IgM indicates a recent infection while IgG indicates a previous exposure or secondary infection. The Antibody test detects both IgM and IgG antibodies. A blood sample is used for both tests which provide quick results. With an accuracy of 75–95% and a sensitivity of 80–90% respectively the NS1 and IgM/IgG tests help to diagnose and treat Dengue.
What is a Dengue Rapid Test Antigen (NS-1) & Dengue Antibody (IgM, IgG) Test?
Dengue Rapid Tests, like NS-1 Antigen and Dengue Antibodies IgM, and IgG, are very important tests to diagnose Dengue virus infection. Doctors prescribe these tests for a patient who shows symptoms of a Dengue fever infection, especially in the case of an outbreak. These tests are an essential means of understanding whether a patient is infected with the Dengue virus.
The Dengue rapid test in Jaipur is able to detect specific markers in the blood that are related with a Dengue infection. The NS-1 antigen is an indicator of the active presence of the virus, while the IgM and IgG antibodies are indicators of the immune response of the body to the dengue virus.
Dengue Rapid Test Parameters
Dengue rapid tests include a number of parameters, and each parameter provides different information about the stage of the infection. All the parameters, when combined together, provide a complete idea about the dengue status of the patient.
Dengue NS-1 Antigen
- NS-1 (Non-Structural Protein 1): This test gives information about the viral protein produced by the dengue virus. This protein is usually detectable in the blood from day 1 to day 5-7 of fever.
Dengue Antibody Parameters
- Dengue IgM Antibody: Measures antibodies that usually occur after IgM, usually 7-10 days after the onset of symptoms, and can last for years. When IgG is positive alone, it indicates a previous dengue infection. When it is a secondary infection, that is, re-infection with a different serotype of dengue, IgG antibodies increase rapidly and significantly, even before IgM.
- Dengue IgG Antibody: This test detects the antibodies that generally appear after the IgM antibodies, usually 7-10 days after the onset of symptoms, and can persist for years. A positive result for the IgG test alone suggests a previous dengue infection. But in the event of a secondary infection (re-infection with a different serotype of dengue), the IgG levels rise very quickly and substantially, even before the IgM levels.
Symptoms That May Need for Test
A Dengue Rapid Test is advised when symptoms arise, particularly in dengue-endemic regions. These symptoms may include:
- Sudden high fever
- Severe headache, especially behind the eyes
- Muscle pain,
- Bone, and joint pains
- Rash few days after fever
- Nausea and vomiting
- Fatigue and weakness
- Minor bleeding manifestations (nosebleeds, gum bleeds)
Benefits of What is a Dengue Rapid Test Antigen Test in Jaipur
The Dengue rapid test in Jaipur helps in the early diagnosis of a Dengue infection, which is aided by immediate medical attention and the prevention of possible complications. There are a number of advantages:
- Early Diagnosis: The NS-1 antigen helps in the early diagnosis of a Dengue infection, which occurs in the first few days of fever, even before the antibodies are formed.
- Differential Diagnosis: It helps in the differential diagnosis of a Dengue infection from other viral fevers, which have similar symptoms.
- Guides Treatment: It helps the physician in taking appropriate measures and also in the early detection of warning signs.
- Epidemiological Surveillance: It is a very important test in the surveillance of a Dengue infection, especially in cities such as Jaipur.
- Quick Results: Rapid tests give results in 15-30 minutes, which is very important in urgent situations.
Preparation for Dengue Rapid Test Antigen (NS-1) & Dengue Antibody (IgM, IgG) Test
Fasting is not necessary for a Dengue Rapid Test. But it is always better to check with your doctor or the diagnostic lab before going ahead with the test. Let them know the date of onset of symptoms, if you have traveled recently, and if you are taking any medications. It is important to remain relaxed while giving the sample. This will ensure a smooth experience. Good diagnostic labs will have trained phlebotomists and proper sample collection procedures.
Normal Range of the Dengue Rapid Test Antigen (NS-1) & Dengue Antibody (IgM, IgG) Test
Unlike the CBC test, which gives results in numerical ranges, the Dengue rapid test gives a qualitative result (Reactive/Non-Reactive or Positive/Negative). This is based on the combination of the markers present:
| Parameter |
Result |
Possible Interpretation |
| NS-1 Antigen |
Positive |
Early acute Dengue infection (usually within 0-7 days of fever) |
| NS-1 Antigen |
Negative |
No early acute infection, or infection beyond the early phase |
| Dengue IgM |
Positive |
Recent primary or secondary Dengue infection (usually 3+ days post-fever) |
| Dengue IgM |
Negative |
No recent infection, or too early for antibody development |
| Dengue IgG |
Positive |
Past Dengue infection, or secondary infection |
| Dengue IgG |
Negative |
No past infection, or too early for IgG development |
The results of these tests should be interpreted by a doctor along with the symptoms and history of the patient.
